使用Volley实现Https请求， Volley SSL 双向自认证证书请求。

代码参照：
https://github.com/yuxiaohui78/volleyHttps

How
to use it.

1.
In AndroidManifest.xml add the VolleyHelperApplication

<application
android:name="xiaohui.volley.VolleyHelperApplication"
...
</application>

In build.gradle

dependencies {
 compile 'com.mcxiaoke.volley:library:1.0.19'
 }

2.
Example:

StringRequest
- HTTP/GET

private void stringRequestGetHttpExample(){

        VolleyDataRequester.withHttp( this )
                .setUrl( HTTP_HOST + IP)
                .setMethod( VolleyDataRequester.Method.GET )
                .setStringResponseListener( new VolleyDataRequester.StringResponseListener() {
                    @Override
                    public void onResponse(String response) {
                        Toast.makeText( MainActivity.this, "HTTP/POST,StringRequest successfully.", Toast.LENGTH_SHORT ).show();
                        tvResult.setText( response );
                    }
                } )
                .requestString();
    }

StringRequst
HTTP/POST

private void stringRequestPostHttpExample(){

        HashMap<String, String> body = new HashMap <String, String>() ;
        body.put( "name", "xiaohui" );
        body.put( "gender", "male" );

        VolleyDataRequester.withHttp( this )
                .setUrl( HTTP_HOST +  POST)
                .setBody( body )
                .setMethod( VolleyDataRequester.Method.POST )
                .setStringResponseListener( new VolleyDataRequester.StringResponseListener() {
                    @Override
                    public void onResponse(String response) {
                        Toast.makeText( MainActivity.this, "HTTP/POST,StringRequest successfully.", Toast.LENGTH_SHORT ).show();
                        tvResult.setText( response );
                    }
                } )
                .requestString();
    }

JsonRequest
HTTPS/GET

private void jsonRequestGetHttpsExample(){
        VolleyDataRequester.withDefaultHttps( this )
                .setUrl(HTTPS_HOST + IP)
                .setJsonResponseListener( new VolleyDataRequester.JsonResponseListener() {
                    @Override
                    public void onResponse(JSONObject response) {

                        try {
                            String s = response.getString( "origin" );
                            tvResult.setText( s );
                            Toast.makeText( MainActivity.this, "HTTPS/GET, JsonRequest successfully.", Toast.LENGTH_SHORT ).show();
                        }catch (Exception e){
                            e.printStackTrace();
                        }
                    }
                } )
                .setResponseErrorListener( new VolleyDataRequester.ResponseErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        tvResult.setText( error.getMessage() );
                    }
                } )
                .requestJson();
    }

JsonRequest
HTTP/POST

private void jsonRequestPostHttpsExample(){
        JSONObject json = new JSONObject(  );
        try{
            json.put( "name", "xiaohui" );
            json.put( "gender", "male" );
        }catch (Exception e){
            e.printStackTrace();
        }

        VolleyDataRequester.withDefaultHttps( this )
                .setUrl(HTTPS_HOST + POST)
                .setBody( json )
                .setJsonResponseListener( new VolleyDataRequester.JsonResponseListener() {
                    @Override
                    public void onResponse(JSONObject response) {

                        try {
                            String data = response.getString( "data" );
                            tvResult.setText( data);

                            Toast.makeText( MainActivity.this, "HTTPS/POST, JsonRequest successfully.", Toast.LENGTH_SHORT ).show();
                        }catch (Exception e){
                            e.printStackTrace();
                        }
                    }
                } )
                .setResponseErrorListener( new VolleyDataRequester.ResponseErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        tvResult.setText( error.getMessage() );
                    }
                } )
                .requestJson();
    }

JsonArrayRequest
HTTP/GET

private void jsonArrayRequestGetHttpsExample(){
        VolleyDataRequester.withDefaultHttps( this )
                .setUrl(HTTPS_JSONARRAY)
                .setJsonArrayResponseListener( new VolleyDataRequester.JsonArrayResponseListener() {
                    @Override
                    public void onResponse(JSONArray response) {
                        String output = "Array length=" + response.length();

                        for (int i = 0; i < response.length(); i++){
                            try {
                                JSONObject json = (JSONObject) response.get( i );
                                String name = json.getString( "name" );
                                output += "\n" + i + " - " + name;
                            }catch (Exception e){
                                e.printStackTrace();
                            }
                        }

                        tvResult.setText( output );
                    }
                } )
                .setResponseErrorListener( new VolleyDataRequester.ResponseErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        tvResult.setText( error.getMessage() );
                    }
                } )
                .requestJsonArray();
    }

3.
Using Self Certified SSL

Replace the certificates client.key.p12 and client.truststore with our own certificates in folder assets
Configure the CertificateConfig.java
Then use the following method to send the request.

VolleyDataRequester.withSelfCertifiedHttps( this )
                .setUrl( You_url)
                .setJsonResponseListener( new YouJsonRequestListener ())
                .requestJson();
